The current Emperor has a total of nine daughters and seventeen sons, except for the youngest Princes and Princesses, all have voluntarily or involuntarily stayed away from Linzi.
Even with the recent death of Jiang Wuqi, they merely performed remote rites and were not summoned back to the capital.
Over the long past, the four Palace Masters of Changle, Huaying, Yangxin, and Long Life have already proven their abilities, standing out among the royal heirs.
The Emperor is willing to give outstanding children more opportunities, but Daqi's resources are not unlimited and cannot be wasted indefinitely in the dragon dispute. The establishments of Huaying, Yangxin, and Long Life Palaces besides Changle Palace were already a completed first round of selection, with the Crown Prince only to be born among these four Palace Masters.
Other Princes and Princesses have stayed away from Linzi to avoid uselessly consuming national resources.
No matter what feelings people harbor.
